The missing vessel from the given sequence: tracing the circulation to and from the placenta, a drop of blood travels in the fetus from the left ventricle to the aorta, to a common iliac artery, to an internal iliac artery, to an umbilical artery, to capillaries in the placenta, to the ductus venosus, to a hepatic vein, to the inferior vena cava, to the right atrium, to the foramen ovale, to the left atrium, to the left ventricle. Introduction: Placenta is an organ that is present during fetus development in placental mammals. The placenta serves as a conducting unit between the fetus and the motherâ€™s body for the transportation of blood, nutrients, and waste products to and from the fetus and the motherâ€™s body. Umbilical cord is present between the developing embryo/fetus and the placenta.

Tell which vessel is missing from the following vascular circuit: Tracing the circulation to and from the placenta, a drop of blood travels in the fetus from the left ventricle to the aorta, to a common iliac artery, to an internal iliac artery, to an umbilical artery, to capillaries in the placenta, to the ductus venosus, to a hepatic vein, to the inferior vena cava, to the right atrium, to the foramen ovale, to the left atrium, and to the left ventricle. (a) umbilical vein, (b) ligamentum arteriosum, (c) internal carotid artery, (d) capillaries in the small intestine.

Locate the following blood vessels (in bold) in the fetal pigl Arteries: aorta (arch)---dorsal to the pulmonary trunk anterior vena cava and posterior vena cava. brachiocephalic artery--- the first branch off the aorta The brachiocephalic artery branches into three other arteries: the right subclavian (passes under the clavicle), and the right and left carotid arteries The right subclavian continues and becomes the right axillary then right brachial artery. The left subclavian artery is dorsal to the brachiocephalic off of the aortic arch Follow the aorta dorsally where it becomes the dorsal or descending aorta , then the abdominal aorta The renal artery that connects the kidney to the medial abdominal aorta At about the level of the renal artery, you may see the very tiny (diameter) gonadal arteries. The abdominal aorta terminates in four branches: the right and left external iliac, and the right and left internal iliac arteries. The…

A young couple that you are friends with gave birth to a new baby. They were told by their physician that the foramen ovale did not close between the right atrium and left atrium (i.e., that their baby has “a hole in her heart”). They know that you are a nurse and have come to you to help them to understand what is going on. Explain both the normal flow of blood through the heart and the flow with the foramen ovale still open. Include in your description the concept of oxygenated and deoxygenated blood.
